A Caribbean-wide tsunami warning system was planned to be instituted by the year 2010, by representatives of Caribbean nations who met in Panama City in March 2008. Panama's last major tsunami killed 4,500 people in 1882. [7] Barbados has said it will review or test its tsunami protocol in February 2010 as a regional pilot. [8] [needs update]
A tsunami earthquake can be defined as an undersea earthquake for which the surface-wave magnitude M s differs markedly from the moment magnitude M w, because the former is calculated from surface waves with a period of about 20 seconds, whereas the latter is a measure of the total energy release at all frequencies.

The warnings were put to use on Thursday when people in the northern portion of California were sent tsunami alerts moments after a 7.0 earthquake struck just off the coast of Humboldt county at ...
Each DART station consists of a surface buoy and a seafloor bottom pressure recording (BPR) package that detects water pressure changes caused by tsunamis.The surface buoy receives transmitted information from the BPR via an acoustic link and then transmits data to a satellite, which retransmits the data to ground stations for immediate dissemination to NOAA's Tsunami Warning Centers, NOAA's ...
More than 150 tsunamis have hit California’s shore since 1800. Most were barely noticeable, but a few have caused fatalities or significant damage. The most destructive tsunami to hit California ...
Twenty years on from the Boxing Day Indian Ocean tsunami, there are still things we do not know about the phenomenon. More than 230,000 people died after a 9.1 magnitude earthquake under the sea ...
Smaller (M w 4.2) earthquakes in Japan can trigger tsunamis (called local and regional tsunamis) that can devastate stretches of coastline, but can do so in only a few minutes at a time. Landslides The Tauredunum event was a large tsunami on Lake Geneva in 563 CE, caused by sedimentary deposits destabilised by a landslide.
The 7.0-magnitude earthquake did produce a small tsunami, but it measured less than two inches in height, according to initial data. The small rise in water did not cause any reported damage and ...
